Jane Goodall is a British primatologist who has spent her career studying chimpanzees and apes in their natural habitats. In 1960 at age 26, she traveled to what is now Tanzania with just a notebook and binoculars to observe chimpanzees. Through patient observation, she became accepted by a chimpanzee troop and made several important discoveries, including that chimpanzees make and use tools, communicate emotionally, and work together in groups to solve problems. These findings challenged existing beliefs that only humans exhibited such behaviors.
